I have this server initialization class:

package magic.app.main;

import org.glassfish.grizzly.http.server.HttpServer;
import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory;
import org.glassfish.jersey.server.ResourceConfig;

import java.io.IOException;
import java.net.URI;

public class Main {
    public static final String BASE_URI = "http://localhost:4747/";

    public static void main(String[] args) throws IOException {
        /* SOME NON-RELEVANT CODE UP HERE */

        final ResourceConfig rc = new ResourceConfig();

        rc.packages("magic.app.resource");
        rc.register(magic.app.main.CorsSupportFilter.class);

        final HttpServer server = GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI),rc);

        /* SOME NON-RELEVANT CODE DOWN HERE */
    }
}

And this filter class which I'm trying to register in the initialization class:

package magic.app.main;

import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.ResponseBuilder;

import com.sun.jersey.spi.container.ContainerRequest;
import com.sun.jersey.spi.container.ContainerResponse;
import com.sun.jersey.spi.container.ContainerResponseFilter;

public class CorsSupportFilter implements ContainerResponseFilter {

    @Override
    public ContainerResponse filter(ContainerRequest req, ContainerResponse contResp) {

        ResponseBuilder resp = Response.fromResponse(contResp.getResponse());
        resp.header("Access-Control-Allow-Origin", Configuration.getHttpAllowOrigin())
            .header("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS");

        String reqHead = req.getHeaderValue("Access-Control-Request-Headers");

        if(null != reqHead && !reqHead.equals(null)){
            resp.header("Access-Control-Allow-Headers", reqHead);
        }

        contResp.setResponse(resp.build());
        return contResp;
    }

}

When I run the app I get this piece of log:

WARNING: A provider magic.app.main.CorsSupportFilter registered in SERVER runtime does not implement any provider interfaces applicable in the SERVER runtime. Due to constraint configuration problems the provider magic.app.main.CorsSupportFilter will be ignored.

I'm working with gradle and this is my app's Gradle build file:

apply plugin: 'java'

repositories{
    mavenCentral()
}

dependencies{
    // IP2C
    compile fileTree(dir: 'libs', include: '*.jar')

    // Jersey + Grizzly
    compile 'org.glassfish.jersey:jersey-bom:2.4.1'
    compile 'org.glassfish.jersey.containers:jersey-container-grizzly2-http:2.4.1'

    // Jersey
    compile 'com.sun.jersey:jersey-core:1.17.1'
    compile 'com.sun.jersey:jersey-server:1.17.1'

    // JSON
    compile 'org.codehaus.jackson:jackson-core-asl:1.9.13'
    compile 'org.codehaus.jackson:jackson-mapper-asl:1.9.13'
    compile 'org.codehaus.jackson:jackson-xc:1.9.13'
    compile 'com.googlecode.json-simple:json-simple:1.1.1'

    // Jersey + JSON
    compile 'com.sun.jersey:jersey-json:1.17.1'
    compile 'com.fasterxml.jackson.jaxrs:jackson-jaxrs-json-provider:2.3.0-rc1'

    // Postgres
    compile 'com.jolbox:bonecp:0.8.0.RELEASE'
    compile 'postgresql:postgresql:9.1-901-1.jdbc4'

    // Mail
    compile 'javax.mail:mail:1.5.0-b01'
}

您在应用程序中混合了 2 个版本的 Jersey（1.x 和 2.x）。在您的Main课程中，您使用的是 Jersey 2.x（包前缀是org.glassfish.jersey），并且您ContainerResponseFilter是 Jersey 1.x 专有 API 的实现。

如果你想使用 Jersey 2.x，过滤器应该从 JAX-RS 2.0实现ContainerResponseFilter 。

如果你想坚持使用 Jersey 1.x，你应该在你的Main类中更改注册（并且还使用 Jersey 1.x 中的 grizzly 容器模块）：

final ResourceConfig rc = new PackagesResourceConfig("magic.app.resource");
rc.getContainerResponseFilters().add(CorsSupportFilter.class);
